EN 61000-3-11 and EN 61000-3-12

Let's start by guessing what the appliance is that these instructions apply to.

Parents
  • Found this guidance  61000-3-3__-3-11_voltage_fluctuations__flicker.pdf (emcstandards.co.uk) which agrees it concerns light flickering and inrush currents. It also states, in the overview on page 4, it is illegal to connect an item if the power supply does not conform to the requirements

    for 61000-3-12 the manufacturer's instructions state "it is the responsibility of the installer or user..." so you could pass the buck on this one;)

  • Perhaps a typo with the decimal point in the wrong place?

  • No, I don't think so ... when we are talking about loads in excess of 40 A (per phase).

    I think the wrong emphasis in the instructions, though, for loads <= 9 kW (otherwise this would appear on the instructions for a lot of domestic showers).
